This question and the reply with the unused pump raises the question
Is the cylinder wall pump a good idea?
I too have on my rebuild a tank with a pump which doesn’t look as if it has ever been connected
how does it work?,is it manual? and is it a completely separate supply from the ‘normal’ pump supply or does that tee off from it in some way?
my thoughts are if its not a lot of good and its manual could it not be used as an occasional feed for the thrashing chains?
All based on ignorance I’m afraid 😳 and not a lot in technicalities either a good diagram would help
